- •
Oilsands mine operations may expose birds to metals and metalloid elements.
- •
Tree swallows ate up to 50% terrestrial insects, likely limiting exposure to metals.
- •
Annual variation in tissue element burden highlights need for multi-year data sets.
- •
Element variability in food is important when interpreting tissue concentrations.
- •
No evidence that nestling tree swallows accumulated metals approaching toxic levels
